Effect of sowing dates, seed rates and integrated nutrition on productivity, profitability and nutrient uptake of summer mungbean in Eastern Himalaya

Abstract

A field experiment was carried out in the summer seasons of 2010-2012 at north eastern hilly region of Jharnapani, India, to evaluate the effect of sowing dates, seed rates and integrated nutrition on productivity, profitability and nutrient uptake of summer mungbean. Experimental results revealed that 5th April sown crop recorded significantly higher growth attributes, yield, and economics than 15th April sown crop. This was mainly because of the fact that almost all the yield attributing characters were favourably influenced because of early sowing and, therefore, yield increased. Similarly, 5th April sown crop resulted in higher cation exchange capacity (CEC) of roots, root N content, nitrogenase activity (NA), total uptake of N, P, K and protein yield than the 15th April sown crop. Higher yield and economics were found with seed rates of 35 kg ha −1 , whereas CEC of roots, root N content and NA were higher at 20 kg ha −1 . Application of 50% RDF (recommended dose of fertilizer) + 50% RDN (recommended dose of nitrogen as vermicompost) + PSB (phosphate solubilizing bacteria) produced significantly higher growth attributes, yield and economics of mungbean.

Influence of Different Sources of Plant Nutrients on Soil Fertility, Nutrient Uptake and Productivity of Soybean under Vertisols

“…FYM application reduced the loss of nutrients through leaching and made available significant amount of plant nutrients, which created a balancing effect on supply of nitrogen, phosphorus and potassium. Similar results were reported earlier by Kumawat et al, (2009b), Kumar and Kumawat (2014) and Yaduwanshi et al, (2018).…”

Nutrient Management in Mungbean [Vigna radiata (L.) Wilczek] for Higher Production and Productivity under Semi-arid Tract of Central India

“…The cumulative effect might be due to supply of nitrogen and phosphorus to the crop and also increased solubilization of mineral phosphates and other nutrients similar observation was recorded by Tanwar, (1997), Kumar et al, (2010) and Kumar and Kumawat (2014). Varying treatments of nutrient management has significant effect on the seed yield, straw yield and harvest index of mungbean (Table 1).…”

Optimizing the Growth and Yield of Mungbean (Vigna radiata L.) Cultivars by Altering Sowing Dates

“…Singh et al (2010) studies also reported significant effect of sowing dates and on plant height. These results were supported by Kumar and Kumawat (2014) who reported significant interaction of mung bean in the case of plant height. The significant effect of sowing date and variety on plant height may be due to differences in the growth periods.…”
